Zex Kits on a 2002 Elantra?
Hey there,
I've been searching the forum on info about the Zex kits, but found one that said the kits wouldn't work on a car with MAP sensors... Could some one tell me if that is right or wrong? I'm looking to run just a 50/55 shot and wanted to make sure before I ordered a kit.
Thanks!!!

wow, your lucky day. there is a zex kit for sale in the 'for sale' forum for only 400$$$ if it works, i suggest you get in touch with the guy who is selling it for cheap. by the way, i believe he said that it would come with a pre exhisting cai that was all ready adapted to the zex application.

The problem with the Zex kit on your engine, is not that it is MAP based. It is the fuel system.
You have a *returnles* fuel system. Zex works by upping the fuel pressure by *fooling* the fuel pressure regulator into raising the fuel pressure. You cannot do this on a *returnless* fuel system, as there is no Fuel Pressure regulator per se.
I would reccomend the Venom kit for your application. The Venom kit taps into your stock fuel injectors, and pulses them for a longer period of time. It also taps into your stock O2 sensor. The kit will shut itself off if you run lean, giving you a good margin of saftey.
Is is the only kit out there that I can think of that will work, and be safe for your engine.
The NX Express *wet* kits should/might do the job, but they do not have a 02 sensor saftey, so would suggest getting a A/F ratio gauge (the venom kit comes with one) to keep track of the NX kit if you go that route.

Alrighty... So Zex is out of the picture. Venom is a VERY smile.gif expensive kit. So, NX would be the way to go and it runs about the same $$ as a zex kit. How much harder is this kit to install than the zex kit? Should I still use zex plugs since they run cooler or are they just a gimmick?
Thanks!

Spatch!</div>The venom kit I think your thinking about is the VCN-2000 which is the fully computer controlled integrated progressive controller with 3 different modes. Venom also has a slightly less expensive kit the VCN-1000 which does not have the progressive controller but is still computer controlled. It runs about $600-700.
Now as far as the NX kit goes the beta engines will only handle the 50HP jet setting which is about equal to a 75 shot dry system like the venom and zex kits. Unless you upgrade the fuel pump then you will be able to handle the 75HP setting. NX currently only has a low fuel pressure cut off for their kits that is optional from the kit. NX will be coming ouit shortly with an A/f ratio cutoff like the venom has. It should be out in a few months. smile.gif And if you spraying I would reccomend using the NGK copper v-power plugs and going 1-2 steps colder of a plug. They are inexpensive and have been popular in a lot of nitrous applications. Do not use platinum plugs. Iridiums are fine but tend to be a little pricey. The copper v's I think run about $2-3 a piece.

the NX kits do not need the colder plugs, as the additional fuel they add so far up the intake air stream does the job of cooling the combustion event. You might want to go 1 heat range colder, but you will have to experiment.
The Venom kit is only $600. That's only about $150 more than the NX/Zex kits. For the added margin of saftey, plus the A/F gauge, it's easily worth it.

Ooops, I didn't notice the 2002.
It's good that Venom brought out a cheaper version of their nice system. I inquired about them a couple of years ago... but their initial prices for their top of the line and only available kit was well over $1000.
With the returnless fuel pumps / regulators, Venom definately has an advantage.
A NX wet kit is not a bad way to go... good solenoids... nice power gains.

The venom vcn-1000 kits seem pretty straight forward compared to the NX kits. How hard are the Venom kits to install compared to the NX kits?
I was going to go with a:
NX Kit w/ 15lb bottle
Gen X 2 Kit
Remote bottle opener.
Can I get that kind of equipment for a Venom kit?
Atleast a bottle opener, auto heat pad, and a purge valve... The cheapest price I can find for a venom kit is $650.00.. Anyone know of a place to get them?
Thanks!

well i was the test dummy for venom
It took me about 3 hours to install the kit by myself,... *i do have nitrous install experience*
650 is a good price
take it
As for are your nitrous stuff,... you can use ZEX and NOS products with the venom kit
purge kits are pretty universal with nitrous kits
so are bottle warmers and all that other stuff you posted
